Question

a man bought 20dozens of eggs at rupees 52 per dozen.on opening the crate he found that 10 percent percent of the eggs were damaged. at what price per dozen he should sell to gain 160 rupees

Answer 1

A man bought 20dozens eggs which is 20*12=240pcs

purchase price was 52per dozen= 52*20=1040/-

10%of 240 eggs were damaged; therefore 10%of240=24 were damaged

Therefore 240-24=216 were ok.

216/12=18dozen were ok.

Now his selling price should be 1040+160=1200

For 18 dozen his selling price is 1200/-

Selling price per dozen is 1200/18= 66.66 per dozen
